They also began increasing the range of their forecast from 15 days to 25 days, 45 days, and (by 2016) to 90 days. These hyper-extended forecasts have been compared to actual results several times and shown to be misleading, inaccurate, and sometimes less accurate than simple predictions based on National Weather Service averages over a 30-year ...
The localized segments provide current weather observations, and high and low temperatures observed since 12:00 a.m. local time for a given city; MinuteCast forecasts, incremental forecasts (pioneered by AccuWeather, Inc. [3]) for the next hour; at-a-glance forecasts for the current day and the day after; extended forecasts (which, in addition ...
ECMWF aims to provide accurate medium-range global weather forecasts out to 15 days and seasonal forecasts out to 12 months. [11] Its products are provided to the national weather services of its member states and co-operating states as a complement to their national short-range and climatological activities, and those national states use ECMWF's products for their own national duties, in ...

Microsoft's Aurora system offers global 10-day weather and 5-day air pollution (CO 2, NO, NO 2, SO 2, O 3, and particulates) forecasts with claimed accuracy similar to physics-based models, but at orders-of-magnitude lower cost. Aurora was trained on more than a million hours of data from six weather/climate models. [83] [84]

Data extrapolation, including development or dissipation, can be used to find the likely location of a moving weather system. The intensity of rainfall from a particular cloud or group of clouds can be estimated, giving a very good indication as to whether to expect flooding, the swelling of a river etc. Depending on the area of built-up space, drainage and land-use in general, a forecast ...
Weather reconnaissance aircraft, such as this WP-3D Orion, provide data that is then used in numerical weather forecasts.. The atmosphere is a fluid.As such, the idea of numerical weather prediction is to sample the state of the fluid at a given time and use the equations of fluid dynamics and thermodynamics to estimate the state of the fluid at some time in the future.
